In order to build a dependency graph of continuation execution and data-fetching in PHP-land, we need a few instrumentation points in the asio_ext HHVM extension. There are 4 additions required: 1. Callback when a continuation finishes successfully. 2. Callback when a continuation blocks on a wait_handle. 3. Get array of WaitHandles a GenArrayWaitHandle is waiting on. 4. Get WaitHandle that the SetResultToRefWaitHandle is waiting on. I don't think this should really affect performance, as in the normal case, nothing has changed, but you never know... I'm also not sure who should be reviewing this, so I've just added @jan for now. If you could pile other people on, that would be cool. sandcastle appears to be broken.
